COLOSTOMY errnrancn.

Application filed li ovember '5, 1926. Serial No.'146,439.

The principal objects of the invention are, to minimize the inconveniences, dlscomforts and handicaps to patients who have suffered a colostomy operation and to provide an appliance which will be thoroughly sanitary and which will enable the ready removal and replacement of the pouch.

The principal features of the invention consist in the novel construction of the pouch, whereby a collar orbead encircling the opening to the pouch is, held in a sealing contact with thebody of the wearer.

In the drawings, Figure .1 is a perspective view of the pouch and retainer showing the ends of the belt straps attached thereto.

Figure 2 is a longitudinal, mid-sectional view on an enlarged scale. l

Figure 3 is a small perspective view of the entire appliance.

F llowing a colostomy operation it is necessar to provide a closure for the incision which will fit snugly to the body of the wearer so that the escape of fluids or gases will be prevented without imposing uncomfortable restriction.

The device comprises a retainer pad '1,"

formed of rubber adapted to fit snugly against the body. The pad is provided with studs 2 embedded in the rubber material to which the loop ends 3 of the belt'straps are detachably secured. The centralportion of,

minates in a hea bea structure 6 which is of an elliptical orm obliquely disposed in tight joint, the socket joint thus relation to the pouch. The elliptical head 6 to fit snugly into the socket flange is shaped 4 of the ad l-with the. pouch protrudin through c o and the outer edgeo the flange socketfits tightly around theneck 7 of a the t'pouch. The cross sectional container of e outer wall of the bead 6 ofthe pouch corresponds with the cross-sectional contour of the inner wall of the socket flange 4 of the retainer pad so that the bead-fits ve snu lyin place and the offt he pa d surrounding th binds u inner edge v8 pen the bead and forms a liquid a socket depression the central per end which terand having a e. opening therein the pad. 7

The bead 6 'is very thick thickness is bedded in the cavity formed'by the flange 4. .The other art protrudes be yond the inner face of t e pad which fits against the bod consequently the protruding thickness 0 the bead beds itself in the body around the incision.

and part of its The bedding of the head in the flesh forms a thoroughly effective seal around the in- ClSlOll against the escape ofany-liquids or feces and all sound from the escape of gases is eliminated. A small relief orifice 9 is pouch. The pouch is of a flat construction having the upper wall. 10 of greater thickvery positive and free movement of the feces.

From this description it will be underpreventing displacement of the pouch in provided in the thick upper shoulder of the,

stood that the patient will sufier the ininimum of discomfort in the use of this appliance and that the onerous conditions entailed By the nature of the surgical opera? tion w' be greatly mitigated.

JThe pad and the belt supporting same are sufliciently flexible to allow the easy drawal of the pouch therefrom and the ready insertion of a. fresh withpouch without either re moving or displacing the' retainer pad, it

being merely necessary to disconnect one of the belt fasteners from the pad 1 whichwill allow the corner to be turned back and when the pouch may be withdrawn. 6

What I claim as my invention is: 1. Acolostomy ap liance, comprising a retainer having a socl et 'depressiomtherein, a central .0 enmg in said socket depression, and a pouc of a size adaptedto be readily inserted throu of the socket depression aroun against the body. 2. A colostomy a lian'ce com a flat flexible rubbepp p mg retaining pad hithe opening in said retainer ,aded edge engaging, he wall having a central orifice formed with a socketdepresv sio'n around its peri hery fastening devices secured-in said pad,

the body detachably securedio' said fastening devices, and a pouch of a size adapted to be readily inserted through the orifice in said pad and having-a beaded edge adapted to fit into saidsocket depresion.

106 Its adapted to encircle 1 formed also -3. A colostomy appl ance, comprising a belt, a retainer pad secured to said belt.

having an orifice therein, and a socket surrounding said orifice, and apouch of a size adapted to be readily inserted and withdrawn through said orifice from the inner side of the pad and having a beaded edge adapted to fit into said socket and toseal against the body.

4. 'A colostomy appliance, comprising a belt, a retainer pad secured to said belt having an orifice therein, said orifice having 'a surrounding flange curved outwardly forming a surrounding socket, and a pouch of ar-size adapted to be readily inserted and withdrawn through the orifice from the inner side of the pad and having a bead adapted to fit into the socket and to project beyond the inner face of the pad, the edge of the pad binding around the head of the pouch in a liquid tight joint.

5. A colostomy appliance, comprising a belt, a retainer pad secured to said belt having an orificetherein and a flange curved inwardly to form asocket surrounding the orifice, and a pouch of a size adapted to be readily inserted and withdrawn through the orifice from the inner side of the pad having a rubber pocket formed with a heavy integral annular bead of circular cross section adapted to fit snugly into the socket formed by the inwardly curved flange to form a seal therewith, said bead projecting beyond the inward face of the pad to be embedded in the flesh of the wearer.

6. A colostomy appliance, comprising a belt, a retainer pad secured to said belthaving a socket depression on the inner side thereof leading to a central orifice and a. rubber pouch of a size adapted to be readily inserted and withdrawn through said orifice from the inner side of the pad and having a
